FE-Simulation of Tyre-Profile-Effects on Terrain Mobility of Vehicles

摘要

Many simulation-models have been established to predict the terrain-mobility of vehicles. Among the models describing the tyre-soil interaction the tyre profile effects are rarely considered. At the IKK a new FEM based simulation model which includes the tyre profile effects has been developed. In this article the new model is introduced. First simulation results are presented an discussed. It can be seen that the simulation results concerning soil deformation, traction forces and slip-sinkage correspond well with natural observations. The new model is able to simulate effects of wheel-soil interaction which are not considered in any other model.
